i played with the wide band today. :metal: i put the sensor in back 02 hole. it looks like i am a little rich at WOT (11.7) and what should one idle and cruise at? mine is at 14.1-14.5 idle and cruise. here is a pic. i marked 2nd and 3rd gear pull.

Should idle and cruise at 14.5-14.8. 11.7 is just right for WOT on a supercharged/turbo car, but very rich on a N/A car.

+1..
On nitrous should be around 12:1 or so and n/a you want between 13.1-13.7 depending on what the car likes.
Also you typically you want to measure a/f in 4th gear. This is because that is where your accurate load values are

i took 12% out at wot and this is what i got in 4th gear. it was around 12.3 in lower rpms then leaned out as they went up. i seen 11.9 at higher rpm. but mainly around 12.0. should i take more out? do i need to do anything else while doing this?

My recommendation.

Try to get in the 13's at 3k rpm to 5k rpm and then let it fatten up to 12.5 or so from 5k rpm up. That should be a optimal starting point until you get to the track then you can start pulling a little fuel at a time out on the upper rpm until it seems to be running its best

the only fuel setting i have is at WOT. i just wonder if the stock T/B and upper intake are restricting air in higher rpms?

Sorry, I meant WOT at the rpm ranges I mentioned in my post

since my last reading took last nite. i took out 12% this morning on the way to work for a total of 24% leaner. it was like 12.1-12.25. so at work i pulled 12% more out. on the way home my first hit i seen 13.8! STOP. and put 8% back in it and got 13.2-13.5. this morning the IAT was 70 and tonight it was 48!!! OPPS:baby: i think i need to put it back rich and wait till a day at the track. this is so cool:metal:
